Technology
Unique I AM WORKING™
function
The One Series provides a continuous indication of its health AND the
switch output status, both locally and remotely. An LED on the front panel
and a discrete logic output signal are used to communicate three states:
- I AM WORKING™ but I Have Not Switched
- I AM WORKING™ and I Have Switched
- I Am Not Working
The One Series I AM WORKING™ feature
diagnoses the health of the sensor, software, microprocessor and power
supply. And it does all this on a continuous basis. Used in conjunction
with the standard switch output, the I AM WORKING™ signal
can even help satisfy many DPDT requirements. Functions of the I AM
WORKING™ signal are as follows:
Signal
|
Interpretation
|
I AM WORKING™
output "On" continuously
|
Normal operation,
unit operating properly
|
I AM WORKING™
output pulsed "On" and "Off"
|
Beyond set point,
unit operating properly
|
I AM WORKING™
output "Off"
|
Loss of power
or unit inoperable
|
100% Set point and deadband adjustment
Set point and deadband values are adjustable over the full range span
using a convenient, simple to operate, front panel keypad. Access to the
programming mode requires a simple, yet tamperproof, keying sequence...
It's better than password protection!
Process variable extremes stored in non-volatile
memory
System pressure or temperature extremes are retained in the One Series'
non- volatile memory, assisting in troubleshooting problems. The One
Series captures high and low pressure or temperature extremes constantly.
Unique switch operating mode
The One Series provides four convenient switch operating modes which
determine the function of the switch output, deadband, LED status indicator
and I AM WORKING™ signal. The desired switch operating mode can
be selected from one of four options:
- High Limit Alarm - Close on Rise
- High Limit Shutdown - Open on Rise
- Low Limit Alarm - Close on Fall
- Low Limit Shutdown - Open on Fall
Excellent media compatibility
Pressure: Wetted materials include a 316 stainless steel pressure connection,
ceramic pressure sensor and your choice of O-ring material. The piezoresistive
ceramic sensor is compatible with most media except a few aggressive acids.
Temperature: 304 stainless steel sensor housing.
